' Application filed November 1, 1915. Serial No. 59,117.

To all whom it may concern:

Be it known that I, CALEB WIMFRY BARR, a citizen of the United States of America, and resident of Knoxville, in the county of Marion and State of Iowa, have invented certain new and useful Improvements in Controlling Devices for Explosive-Motors, of which the following is a specification.

This invention relates to controlling devices for explosive motors and particularly to a device for operating the fuel control, the said invention being more especially designed for use in connection with the accelerators of motors of the type indicated.

An object of this invention is to provide a novel adjustable pedal connected with a lever so that the said lever may be actuated by the movement of the pedal, means being provided as stated, whereby an adjustment is permitted so that the pedal may be moved to different angles of adjustment to suit the convenience and comfort of the user.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification denote corresponding parts in the several views, and in which Figure 1 illustrates a view in perspective showing the accelerator operating mechanism; Fig. 2 illustrates a view. in side elevation of the device shown in Fig. 1'; Fig. 3 illustrates a sectional view on the line 3-3 of Fig. 2; Fig. 4 illustrates a sectional view on the line 44 of Fig. 3 omittingthe supports for the pivot, and the fragment of the bed or body of the vehicle which is shown in the other figures; Fig. 5 illustrates a view in elevation of operating mechanism embodying a modified construction; Fig. 6 illustrates a sectional view on the line 66 of Fig. 5; Fig. 7 illustrates a sectional view on the line 77 of Fig. 5; Fig. 8 illustrates a sectional view on the line 8-8 of Fig. 5; and Fig. 9illustrates a sectional view on a line corresponding with the line 99 of Fig. 8.

In these drawings 5 denotes the floor of the body of a vehicle, a fragment of which is here shown, 6, 6, brackets forming bearvenience and ease ings-or supports for a pivot .or pin 7 which constitutes a fulcrum for the lever 8, the upper end of which terminates in a head or disk 9, one face of which is supplied with serrations or teeth 10. 'The lower end of the lever 8 has a link 11 which leads to any part of a motor control and as the manner of connecting this link to such control is an immaterial detail of construction, it is not shown.

The pedal 12' has a shoulder 13, a flange 14 and lugs 15 which are adapted to prevent dislodgment of the foot from the pedal when the pedal is being operated and said pedal is connected to or formed with a disk avlng serrations or teeth 17 adapted to interlock or engage the teeth 10 of the head 9; the members 9 and 16 being provided with apertures 18 and 19 respectively to receive the pivot 7 on which the members partially rotate.

he manner of assembling the pedal and disks 16 is shown herein and is intended to disclose one embodiment of the invention and, as has been stated the pedal may be moved to dilferent positions for the convenience of the operator and the foot of the operator is not likely to be dislodged from the pedal when pressure is applied as means are provided for holding the foot in place. In the modified construction, the operatmg mechanism includes a pedal A which is secured to a disk A, the said disk having serrations A on one face. The disk is mounted on a shaft A carried by a bracket A. A beveled gear wheel a is also mounted on the shaft A and the gear wheel has serrations a which interengage the serrations of the disk, the said disk and gear wheel being .held in assembled relation by a fastening a on one end of the said shaft. The gear wheel a meshes with the gear wheel C on a vertically disposed shaft .0, the lower end of said shaft 0 having a cross arm 01 to which links 6 and f are connected, which links may lead to controls of a motor, such as the carbureter or cut out or to the spark advancing or retarding mechanism of an ignition system. The utility of these con: nections and their exact use is not a material feature, but the means for operating them by an adjustably arranged pedal for conof operation is included as a part of the said invention.

By reason of the last mentioned construction, the. pedal may be adjusted to a horizontal or inclined position without disturbing the link connections, that is when the disk and gear whe'el are disconnected and when the parts are reset, the movement of the pedal will be communicated to the links.

I claim- 1. In an operator for accelerators, a lever having a head, at one end, the said head having its face provided with serrations, a disk having serrations adapted to interengage with the serrations of the head, said head and disk having coinciding apertures, a pivot in the said apertures, means for supporting the pivot, a pedal having foot engaging devices, and means for connecting the pedal to the disk.

2. In an operator for accelerators, a lever, a head on one end of the'lever, said head having serrations on one of its faces, a disk having serrations interengaging with the serrations of the head, said head and disk having coinciding apertures, a pivot in the the second mentioned gear Wheel is mounted,

a cross arm on the said shaft, and links connected to the ends of the arm.

In testimony whereof, I affix my signature in the presence of two witnesses.
